    摘要： A method and apparatus for monitoring a subject's autoregulation function state is provided. The method includes: a) continuously sensing a tissue region of the subject with a tissue oximeter, the sensing producing first signals, and determining frequency domain tissue oxygen parameter values; b) continuously measuring a blood pressure level of the subject using a blood pressure sensing device, the measuring producing second signals, and determining frequency domain blood pressure values; c) determining a coherence value indicative of the subject's autoregulation state in each of a plurality of different frequency bands; and d) determining a peak coherence value indicative of the subject's autoregulation state based on the determined coherence value from each of the plurality of different frequency bands.

    摘要： A bed system including an acquisition unit and a display, in which the acquisition unit acquires user interface device information from a plurality of user interface devices and the display displays a plurality of images corresponding respectively to the plurality of user interface devices on a single screen based on the user interface device information. One set of the plurality of user interface device information includes state information including at least one of bed state information relating to the state of one bed among a plurality of beds and user state information relating to the state of a user of the one bed among the plurality of beds. One image among the plurality of images includes a state display corresponding to the state information. When the state information is abnormal, the first display displays a warning display on the one image among the plurality of images.

    摘要： Embodiments provide a reliable, convenient, noninvasive, and cost-effective determination of structural and valvular abnormalities in the left ventricular outflow tract. Embodiments obtain a noninvasive optical pulse plethysmogram from the systolic and diastolic phases of the cardiac cycle for subsequent morphologic waveform analysis to determine left ventricular outflow tract anomalies. Left ventricular outflow tract abnormalities alter the rate of increase in flow during early systole and decrease in flow during late systole. These flow variances at the aortic valve are amplified as the pulse wave moves to the periphery due to a combination of the ventricular-aortic interaction, pulse augmentation, and reflections at branching vessels and changes in diameter. The invention addresses historical limitations in the noninvasive determination of structural and valvular abnormalities in the left ventricular outflow tract by using one or more of (1) improved optical measurement systems, (2) peripheral sampling locations that maximize signal differences, (3) volitional patient maneuvers to improve the diagnostic ability of the system, and (4) pulse enhancement techniques. The resulting test system can be used to determine the presence of abnormalities and to diagnose the type of abnormality. The ability to more efficiently and effectively diagnose aortic stenosis, the most common abnormality, in the primary care clinic will result in fewer patients experiencing complications such as heart failure, heart attack, and sudden death.
